The Fantech 5DDD18EB is designed to offer perfect ventilation in industrial, institutional and commercial kitchens. It can effectively exhaust foul odors, fumes, smoke and grease-laden vapors from commercial kitchen spaces and can operate at airstream temperatures of up to 300 F. The backward inclined aluminum fan wheel expels a lot of air and the fully welded windband ensures leak-proof construction. It also has an externally cooled motor compartment to extend the life of the motor. The ventilator is UL 762 listed for restaurant exhaust and UL 705 for electrical applications.
